Okay, i tried it with a new private int-variable which contains
the current index of the for-loop, like this:
private void letButtonsFlash(){
foreach(Button btn;bArr){
btn.setSensitive(false);
}
for(int i = 0; i < level; i++){
index = i; //index is public
Button currentButton = bArr[rndButtonBlink[i]];
ListG list =
currentButton.getStyleContext().listClasses();
string CSSClassName =
to!string(cast(char*)list.next().data);
currentButton.getStyleContext().addClass(CSSClassName
~ "-flash");
Timeout t = new Timeout(&timeout_delay,1,false);
}
foreach(Button btn;bArr){
btn.setSensitive(true);
}
}
bool timeout_delay(){
Button currentButton = bArr[rndButtonBlink[index]];
ListG list =
currentButton.getStyleContext().listClasses();
string CSSClassName =
to!string(cast(char*)list.next().data);
currentButton.getStyleContext().removeClass(CSSClassName
~ "-flash");
return false;
}
But now the strange thing happens, that the first button lights
up as expected but the second button remains at its "flash color"
and doesn't go back to normal color, i don't understand why this
happens? Any ideas?

Thanks a lot for your answer, i tried it like this and it works:

You should change the css class in the timeout_delay function.
It's called by the GTK main loop every time the amount of seconds passed
to the constructor has passed. And return true if you want to continue
to flash the button, and false to stop.
Also don't sleep in the timeout function, the main loop should take care

As I said about x86_64 being backwards compatible with x86 (you can even run old 386 programs on a modern day cpu, go figure) so that isn't the problem. Maybe the Alpine Linux package for Wine has only 64-bit support... Maybe, Linux is finicky here library wise. Usually both arch binaries are required library wise and since Alpine is minimal.. easy to assume. The reason why we do not provide a dmd compiled for 64bit is simply, 32bit works in pretty much all cases. The cases it doesn't involve very large code bases being compiled. I understand, but what's exactly the problem in providing a 64bit version of the executable? Not providing it has just complicated my experience with D... :-) You're the first in over six months to bring up this issue, so not a common requirement ;) I just had a look into Wine, I'm not sure if this helps[0]. Right now you're not creating a new Wine environment or configuring it. I think that the 'wineboot' command in the Dockerfile just do it: I can run Win64 console application... Based on what I read, wineboot handles an instance lifetime e.g. restart. So killing of processes and getting mounts in for example. The link I gave has an example of a program that configures a new instance of Wine that is 32bit (since you can't change a 64bit one to 32bit) which is not the same thing. Otherwise, can you change over to a 32bit image instead of 64bit alpine? That probably will also fix it. Probably yes, maybe with an Ubuntu image as a base. The point is that everyone in docker is switching to Alpine distributions, as an alpine based image is far smaller that the other options, and the official Docker image of Alpine is 64bit only Given this information, yeah it might be worthwhile to distribute a build of dmd that is 64bit for Windows. But this won't allow you to execute the produced programs under Wine. Since you can't execute 32bit programs and since you can't really install MSVC or the required programs/libraries from Microsoft your stuck there. So really you want to get this sorted out.

The command is invalid. with WINEARCH=win32 /dmd2/windows/bin # wineconsole dmd.exe wine: '/root/.wine' is a 32-bit installation, it cannot support 64-bit applications. As I said about x86_64 being backwards compatible with x86 (you can even run old 386 programs on a modern day cpu, go figure) so that isn't the problem. Maybe the Alpine Linux package for Wine has only 64-bit support... The reason why we do not provide a dmd compiled for 64bit is simply, 32bit works in pretty much all cases. The cases it doesn't involve very large code bases being compiled. I understand, but what's exactly the problem in providing a 64bit version of the executable? Not providing it has just complicated my experience with D... :-) I just had a look into Wine, I'm not sure if this helps[0]. Right now you're not creating a new Wine environment or configuring it. I think that the 'wineboot' command in the Dockerfile just do it: I can run Win64 console application... Otherwise, can you change over to a 32bit image instead of 64bit alpine? That probably will also fix it. Probably yes, maybe with an Ubuntu image as a base. The point is that everyone in docker is switching to Alpine distributions, as an alpine based image is far smaller that the other options, and the official Docker image of Alpine is 64bit only

The only platform this may not be true for is OSX where 32bit is long dead globally and 64bit is the only option. Sadly Windows and Linux still have 32bit cpus common in the last 10 years.

it is true, perform the branch.
Of course I meant:
match!(T,
int, () {writeln("Matched int");},
is(T : SomeObject), () {writeln("Derives from
SomeObject");}
);
You could probably even match on the actual value (instead of its
type) and pass it (correctly casted) to the functions:
match!(t,
int, (int t) {writeln("Matched int ", t);},
is(T : SomeObject), (SomeObject t) {writeln(t, " derives
from SomeObject");}
);
I don't have time to implement it now, but I think it's not too
difficult.
Re: static switch/pattern matching
also, there is a subtle bug in matcher. sorry. ;-)

note that you should separate type names from labdas with ","
instead of doing `int => "integral`, and have to add `()` at the
end to actually call the delegate.

Something like this would be ideal...
